Description
Technical field
The invention belongs to metal corrosion and protection technical field, particularly relate to the preparation method of anti-oxidant, the thermal etching protective coating of a kind of hardware of being on active service under the high temperature conditions and parts.
Background technology
Ferrous materials is the best price/performance ratio structured material that the world generally applies.But under high temperature oxidation stability atmosphere, the surface oxidation problem of ferrous materials is extremely serious, and high temperature oxidation causes the loss of metal, reduces effective bearing cross-section of equipment unit, reduces the mechanical property of material, seriously reduces the work-ing life of equipment.Because ferrous materials is the most cheap available metallic substance on the current earth, even if in high temperature environments, ferrous materials is faced with serious problem of oxidation, and at many industrial circles, iron and steel remains the most widely used structured material in main equipment and parts manufacture.The reduction distillation reactor etc. used as the annealing pot of smelter application, heating-furnace bottom tube and titanium sponge production is all typically used example.
In order to reduce the oxidational losses of ferrous materials in high temperature environments, people have carried out a large amount of experimental studies, find terms of settlement.The antioxidant property of metallic substance depends on that this metallic surface forms the character of oxide film; Al, Cr, Si are the important alloying elements of superalloy composition; these elements preferential oxidation in high temperature environments; generate stable, fine and close, protectiveness excellent oxidative film at alloy surface, effectively can stop the high temperature oxidation process of alloy.Using nickel base superalloy or containing high Cr-containing alloy steel is the terms of settlement first expected.But superalloy is expensive, even if relatively cheap high Cr-containing alloy steel is also tens times of plain carbon stool price.High temperature anti-oxidation coating is also the effective method of one reducing burning loss, especially the inorganic high-temp oxidation resistant coating prepared of slip cladding process, and it is with easy to make, with low cost.Because the protection that the metallic matrix of required protection is different and concrete requires different, the coating of different performance correspondingly just need be adopted.Because the bonding strength of inorganic high-temp antioxidant coating and matrix metal is very weak; and it is larger with the thermal expansion coefficient difference of matrix metal; they can only cover the surface of high-temperature component usually momently; protected; but under being in the Working environment of high temperature (more than 900 DEG C), load-bearing, oxidation and thermal etching (nearly 2000 hours of the production cycle) for a long time the reduction distillation reactor used as titanium sponge production; the high temperature service of working conditions very severe, nonmetallic antioxidant coating is difficult to play obvious protected effect usually.Metallic surface hot dipping or solid phase diffusion aluminising are also the effective ways solving ferrous materials high temperature oxidation.After Diffusional aluminizing, the antioxidant property of ferrous materials significantly improves.Owing to being subject to the restriction of hot dipping container, be widely used for the parts of small volume.
Such as, the volume of the reduction distillation reactor of titanium sponge production is comparatively large, more than twenties cubic metres, and nearly 3 tons with material.Enterprise domestic at present uses mild steel plate to manufacture reduction distillation reactor usually.Have complete processing simple, cost of manufacture is low, the titanium sponge Cr of production, the series of advantages such as Ni content is low.But because common carbon steel board intensity is low, oxidation-resistance is very poor, access times are generally about 10 times, and some enterprises consume a hundreds of reactor every year.Under titanium sponge production condition, the outside surface of reactor is chronically exposed in high temperature oxidation and corrosive environment, generate thick large, loose scale gradually, not only consume matrix metal, also reduce the heat-conduction coefficient of reactor, add the consumption of the energy, and in the heat stage, the oxide skin come off also can cause short circuit, the damage of electrical heating wire, blowing out of having to, therefore, the decline of Sponge Titanium quality is caused.
For these problems, some external titanium sponge enterprises adopt stainless steel or high temperature steel to manufacture reactor.Such as, Japanese Patent ［ JP61012836 ］ proposes to adopt SUS410 stainless steel to manufacture reduction reactor.Stainless steel veneer manufacture reduction distillation reactor due to intensity high, corrosion resistance is excellent, long service life, is applied.But the alloying element in stainless steel easily enters among material, especially Ni element has very large solubleness in Mg, will cause the quality degradation of Sponge Titanium.In addition, stainless manufacturing cost is higher, is all the restrictive factor of its widespread use.In December, 2008, Chinese patent (application number: 200810140890.0) propose and adopt carbon steel and austenite stainless steel composite board to make the method for titanium sponge distillation reactor.Adopt the carbon steel sheet one side of adequate thickness as reactor internal layer, the outside of reactor is high Chromiumnickel Austenite Stainless Steel.This thinking is fine, and carbon steel support strength, stainless steel provides high temperature protection.The problem of practical application is, the cost of this composite board reactor is several times of overall carbon steel reactor, and is difficult to the supply ensureing material requested.Domestic somebody directly welds coated one deck stainless steel sheet outside carbon steel reactor.Due to the thermal expansion coefficient difference by stainless steel and carbon steel, Heat Conduction Problems, welding and repair welding problem, and the impact of the factor such as production cost, these methods are not also generally accepted by titanium sponge production enterprise.
Summary of the invention
Goal of the invention: the invention provides a kind of for the preparation of ferrous materials high-temperature protection coating method, the method is utilized to protect, the large high-temperature equipment working life in high temperature environments such as distillation reactor, annealing pot that soft steel manufactures can be extended, reduce production and application cost.
